Introduction. We studied the rate of agreement between the clinical and the radiological diagnoses in acute colonic diverticulitis, analyzing the therapeutic implications.
Patients and method. We present a retrospective study of 140 patients (65 men and 75 women) who were admitted for emergency treatment of clinically diagnosed acute colonic diverticulitis between May 1991 and May 1997. We compared the clinical diagnosis with the radiological diagnosis (abdominopelvic computed tomography) and reviewed the indications and the surgical techniques employed.
Results. In 25% of the patients (n = 35), the clinical diagnosis was not confirmed by radiology or endoscopy. Medical treatment was successful in 104 patients. Forty-seven surgical procedures were carried out in the remaining patients, 30 to treat acute abdomen, 6 after failure of the medical treatment and 11 as elective surgery.
Conclusion. In view of the correlation we observed between the clinical severity and the radiological findings, we consider abdominal computed tomography to be the most reliable complementary diagnostic method in these patients. Given the number of emergency procedures performed, this complementary test should be used much more frequently in the emergency room both as an aid in the diagnosis of acute abdomen and as a guide in the placement of percutaneous drainage
